Blob Storage
In plain terms
Cloud storage for large unstructured objects.
Going deeper
Blob (Binary Large Object) storage holds files like images, videos, and backups at scale, accessed over HTTP. It's object storage in Azure's terms.
Under the hood
Tiered storage (hot/cool/archive) optimizes cost; analogous to AWS S3.
Examples
Image/video hosting, backups, data lakes, static assets, Azure storage.
Think of it like...
Like an infinitely-expandable cloud locker for any kind of file.
